Hadromychus chandleri , new species

Etymology. Patronymic; the specific epithet honors Donald Chandler, one of the collectors of this species.

Type­Material. Holotype (Ƌ) labelled: ‘‘CAN: NS: Halifax Co: Campbell Hill mature red spruce forest FIT: 2 Jun–15 Jun 1997 Coll. DeLancey J. Bishop/ Holotype Hadromychus chandleri Bousquet & Leschen. ’’ The specimen is deposited in the Canadian National Collection of Insects, Ottawa.

Description. Length of body: 2.0– 2.2 mm. Body dorsally light to dark reddish brown, the elytra, except for wide submedian band, usually paler than forebody. Microsculpture of points and meshes present on labrum and anterior portion of frons. Pronotum transverse (LP/WP = 0.68–0.73; 0 = 0.71), distinctly wider than head (WP/WH = 1.40– 1.49; 0 = 1.43), with lateral margin subparallel, except for inconspicuous sinuation near middle, somewhat obliquely subtruncate before anterior angle; area between lateral margin and sublateral carina narrow; punctuation moderately fine, distance between punctures on average slightly greater than their diameter. Elytra long (LE/LP = 2.74–3.00; 0 = 2.84), distance between punctures on average equal to their diameter. Metasternum with very fine, sparse punctures anteriorly and laterally, with slightly coarser and denser punctures medioposteriorly.

Geographical Distribution. The species is known only from a small area in northeastern North America ( Fig. 4 ). It ranges from Nova Scotia westward to southern Ontario.

Habitat. The only information regarding the habitat requirements of this species come from specimen labels: two specimens were collected by flight interception trap placed in a red spruce forest and one specimen was collected by shifting ‘‘conifer log.’’ A single dissected specimen had its gut packed with spores lacking an apiculus, which are probably conidiospores, and some hyphae indicating that H. chandleri is mycophagous like most species of the family Endomychidae .
